The difference between a standard MSD box and your standard ignition is a
boost in primary voltage. Instead of 12-volts primary power being
introduced to the coil, the MSD box boosts the voltage to 270-volts. On an
MSD Blaster SS coil I believe the 270 gets boosted to 48K-volts secondary.
Std ignition and MSD Blaster coil nets about 28K-volts at the plugs. What
does all this buy you? Better ignition and more complete combustion.
That's why your gap can be opened up with an MSD box. 48K-volts can jump
farther than 28K-volts.

That's what I'm inclined to believe also, the 98 had the MSD on from around
10K until I sold it at 45K and bought the 95, it was on both trucks with
fresh Mopar cap/rotors and Mopar/MSD wires, and also on the 95 I've used
Accel and Mopar cap and rotor. With all these changes the only real
difference I felt was with the MSD box itself. Maybe someone out there could
verify if there is some contributing factors in the OBD-I vs. the OBD-II
systems.
